Description of the invention: In the technical field of the invention, the communication secret of the algorithm is related to the communication secret of the algorithm. The multi-coded composite transmission channel (ccTrCH) has one or (ccix:m ^迢丁忙扭) 'It contains 'all the required quality transmission channels (TrCHs) in the coded composite transmission channel H). The prior art rate Γ 3-step code division multiple access (3GW_CDMA) system uses the power and the previous method. The dynamic power control system is applied to the exclusive object 而' and the transmission power of the dedicated physical channel (DPCHS) is adjusted to the service quality (10) with the minimum transmission level, and the degree of interference in the system. This exclusive half is divided into two parallel processing operations: inner loop power control (ILpc) and outer loop power control, LPC). The inner loop power control (LPC) algorithm controls the transmit power to maintain the signal-to-interference ratio (SIR) received by each dedicated physical channel (DPCH) as close as possible to the target signal-to-interference ratio (SIR). The outer loop power control (OLPC) algorithm controls the target finger-to-interference ratio (SIR) of each coded composite transmission channel ((::::::1 €11) to maintain its reception quality as much as possible Target quality. In other words, the output of the outer loop power control (0LPC) is used to update the target signal-to-interference ratio (arc) required for inner loop power control (ILPC). A coded composite transmission channel (CCTrCH) may be multiple The block error rate (BLER) composed of the transmission channels (TrCHs) and the parent transfer channels (TrCHs) are respectively specified. All the transmission channels (TrCHs) located in the coded composite transmission channel (CCTrcH) are simultaneously utilized. The Ring Power Control (ILpc) Transmission Power Control (TPC) command controls 'so that' the outer loop power control (Qjjpc) must select a target signal-to-interference ratio (SIR) value to fully reach all of the respective transmit channels (TrCHs).

Figure 2 illustrates a flow diagram of a method 2〇〇 using the outer loop power control (OLPC) to achieve the quality of service (q〇s) requirements in accordance with the present invention. The method 200 is initiated by selecting an initial reference transmission channel (TrCH) (step 2〇2). A method of confirming whether the initial reference transmission channel (TrCH) is in a steady state is performed (step 204). When a transmission channel (TrCH) is in a stable state, it means that the transmission channel (TrCH) reaches its block error rate (BLER) requirement. If the initial reference transmission channel (TrCH) is not in a steady state, then the far method 200 waits in step 204 until the initial reference transmission channel is in a steady state. If the initial reference transmission channel (TrCH) is in a steady state, a new reference transmission channel (TrCH) is selected to find the transmission with the worst relative block error rate (BLER) during an observation period.

The method 20 〇 206 is until the coded composite transmission channel (CCTrCH) is located, and a transmission rate (TrCH) with a blast rate (BLER) is detected. The:==r(TrcH) is selected as the most pass: the channel condition of 4= rate is known, then 芩k迢 is selected, without the block error rate (BLER> 々 measurement. The confirmation step of the ride condition is money change (step '210). There is a description about the final reference two m method. For example, the user uses the multipaths ^l^ - For a long period of time, if there is no looping excess of 1258933 (the A's side block error rate (BLER) is much lower than the target block error rate (bler)), the meaning of A is that the channel condition has been improved. If the channel condition has not changed, the method 200 waits in step 21〇 until the floor condition of the channel condition changes. If the channel condition has changed, then transitions to the original Zhuka transmission channel (TrCH) (step 212). The outer loop power control (〇Lpc) is executed using the initial reference transfer channel (TrCH). A confirmation step as to whether the initial reference transfer channel (TrC H) returns to a steady state is performed (step 214). The initial reference transmission channel (TrCH) has not returned to a steady state, then the method 2 Waiting in step 214 until the initial reference transmission channel (TrCH) returns to a steady state. If the initial reference transmission channel (TrCH) is in a steady state, then it transitions to the final reference transmission channel (TrCH) (step 216) Outer Loop Power Control (OLPC) is performed using the final reference transmission channel (TrCH). The method 200 returns to step 210 to estimate if the channel condition has changed. Only one transmission channel (TrCH) is located. In the case of a coded composite transmission channel (CCTrCH), the initial reference channel is identical to the final reference channel, in other words, there is no change in the reference channel. Figure 3 illustrates the selection of an initial reference transmission channel (TrCH). Method 300. The method 3 is initiated using a confirmed transmission channel (TrCH) of the coded composite transmission channel (CCTrCH) (step 302). If in the coded composite transmission channel (cCTrCH) There is only one transmission channel (TrCH), then the transmission channel (TrCH) is selected as the only initial reference transmission channel (TrCH) (step 304), and the method is terminated (step 306). If there is more than one transmission channel (TrCH) in the coded composite transmission channel (CCTrCH) (step 302), the transmission channel (TrCH) having the highest block error rate (BLER) is selected (step 308). More than one transmit channel (TrCH) with the same highest block error rate (BLER) value will have a acknowledgment action (step 310). If only one transmit channel (TrCH) has the highest block error 1258933 error rate (BLER) The highest block error rate (BLER) value, then the transfer channel (TrC is selected as the initial reference transfer channel (TrCH) (step 3丨2), and the method ends (step 306). If there is more than one transmission channel (TrGH) with the highest block error rate (BLER) and the highest block error rate (BLER) value (step 31〇), then f has the shortest transmission time interval (tintin 1) transmission channel (Tr CH) is then selected as the initial reference transmission channel (TrCH) (step 314), and the method is terminated (step = . 306). In the method 200, the initial reference transmission channel (TrCH) selection method 300 is executed after the conversion reference transmission channel (TrCH) is not performed thereafter. Other methods assume that the match rate characteristic is selected using a balance between all transmit channels (TrCHs) in the coded composite transmit channel (CCTrCH) and the associated demand target block error rate (BLER). Therefore, if the block error rate (BLER) of a transmission channel (TrCH) is achieved, the block error rate (BLER) of all the transmission channels (TrCHs) located in the coded composite transmission channel (CCTrCH) is also achieved. This allows any transport channel (TrCH) to be selected as the test transport channel (TrCH).
